Pumps are devices used to move fluids by mechanical action.

• Centrifugal pumps use centrifugal force to move fluids.

• Reciprocating pumps use a piston or plunger to create pressure and move fluids.

• Diaphragm pumps use a flexible diaphragm to displace fluids.

• Gear pumps use rotating gears to move fluids.

• Vane pumps use sliding vanes to move fluids.

• Examples of pumps include water pumps, fuel pumps, and hydraulic pumps.

Enthalpy formula is used to calculate the heat content of a system at constant pressure.

• Enthalpy (H) = Internal Energy (U) + Pressure (P) x Volume (V)

• It is often used in thermodynamics to analyze energy changes in chemical reactions

• Enthalpy change (∆H) can be positive (endothermic) or negative (exothermic)

• Function Block Diagram uses blocks to represent functions and their connections.

• Sequential Function Chart is used for sequential control applications.

• Structured Text is a high-level programming language similar to Pascal.

• Inst...read more

There are two main types of motors: AC motors and DC motors.

• AC motors: Alternating current motors that are commonly used in household appliances and industrial applications.

• DC motors: Direct current motors that are often used in battery-operated devices and automotive applications.

The formula for the 3rd law of thermodynamics is S = 0 as temperature approaches absolute zero.

• The third law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.

• The formula for the third law of thermodynamics is S = 0 as the temperature approaches absolute zero.

• This law implies that it is impossible to reach absolute zero temperature.

• The third law is often used to calculate the entropy of a system at absolute zero.

Entropy of water is a measure of disorder or randomness in its molecular structure.

• Entropy of water increases as it changes from solid (ice) to liquid (water) to gas (steam)

• Entropy is a thermodynamic property that quantifies the amount of energy in a physical system that is not available to do work

• Water molecules have more freedom of movement in liquid form compared to solid form, leading to higher entropy
